The analysis of literature data on current-voltage characteristics (CVCs) and permeability of electromembrane systems in the processing of technological solutions of various industries is given. It is noted that electromembrane systems containing porous semi-permeable polymer membranes are insufficiently studied. The results of experimental studies on the CVCs of a membrane system equipped with an anode UAM-100, MGA-95 and near-cathode UAM-100, MGA-95 membranes during the separation of a model solution containing Mg2+, Fe2+, ions are presented. It is shown that in the study of membrane systems equipped with porous membranes, under the action of voltage and transmembrane pressure, as a result of the treatment of the model solution, two characteristic periods are noted on the CVCs (out-of-limit mode, intense electroosmotic transfer).

The reasons for the formation of varnish deposits of turbine oils are determined. It is shown that the performance of turbine oils is determined by methods of ASTM D7843 (MPC) and ASTM D6971 (RUL) can be assessed, the process of formation of varnish deposits, the level of antioxidant properties, antioxidant content of, amend, and extend the oil change, and to predict critical situation in the operation of turbine equipment. The mechanism of formation of varnish deposits in turbine oils is proposed.
